Specification of Letters Patent.

mama Apr. 7, mm.

To all whom it may concern Be it known that I, ERNEST G. B'ARTH, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Steam-Heaters, of which the following is a specification.

This invention relates to certain new and useful improvements in steam heaters, and

the objects thereof are to provide improved means for the instantaneous production of steam.

Further, the invention aims to provide a heater which has improved water containing sections that exhaust the heat from the sections and then cause same to act on the heat from the burners to efiect the rapid formation of steam.

In the drawings: Figure 1 is a front elevation of the invention.- Fig. 2 is a vertical transverse sectional view. Fig. 3 is a vertical longitudinal view. Fig. 4. is a section on the line 44 of Fig. 2. Fig. 5 is a section on the line 55 of Fig. 2, and Fig. 6 is a detail view in top plan of one of the burner manifolds.

The heater consists of a body 1 that has a horizontal gas supply pipe 2 connected thereto, the pipe 2 being common and connected to a series of depending pipes 3, each of which latter have a rotatable valve 4, the stems of which valves are provided with arms 5. The outer'or free ends of the arms 5 are pivoted to a horizontal bar 6 which latter is common to all of the arms and serves to actuate the same in unison to thereby regulate the valves so as to increase or diminish the supply of gas. One end of the bar 6 is pivoted to one arm of'a bell crank lever 7 at 8, the lever 7 being pivotally supported at 9 from the body 1. The other arm of the lever 7 is connected to a chain or other flexible element 10 which latter passes over a wheel 11. The wheel 11 is rigidly secured to a shaft 12 which latter is operated so as to be partially .revolved by the customary diaphragm pressure regulator, not shown. A weight 13 acts as a counterbalance. for the lever 7. An electric lamp or hell 14 is included in an electrical him or sound the hell, by a'contact 15 on .the ever 7 which engages with a contact 16 that is included in said circuit, whereby should the regulator fail to work, the weight 13' will move down, thereby moving the contact 15 into" engagement with the con-tact 16, closing the circuit through the lamp or bell and thus signaling to the operator the fact that the apparatus is working improperly.

Preferably there are three series of water coils 17,'each series consisting of three coils the latter arranged longitudinally of the body shown in Fig. 3. A manifold, shown in Fig. 6, is used to supply gas toeach of the three gas burners 18 of a series of water coils. Each manifold consists of a long outer pipe 19 that supplies gas to the rear- I most burner, a .short' central pipe 20 that supplies gas to the front or forward burner, and a second outer pipe 21 of intermediate length that supplies gas to the intermediate round the burners and coils, while the rearmost section in addition has a back vertical water space 24, the several sections being packed in the usual manner by soft copper gaskets and being held together by long tie bolts 25, which extend through openings 26 that are formed in the abut-ting faces of adjacent sections and register to form water passages, thus providing intercommunicating sections. The upper portion of each section 23 is formed with two series of vertical heat flues 27 the hues of each of which series communicate with common horizontal flues 28 that in turn are connected to a series of lateral horizontal flues 29. Flues 27 overlie the water coils, and the outer ends of the flues 29 extend through the outer sides of the sections 23 whereby the heat after passing through said flues 29, enters the space between the outer sides of the sections and the body 1 and escapes through thedischarge fl'ue 30. The flues 29, as depicted in Fig. 3 0f the drawings, are formed by and between the abutting portions of adjacent" sections. water coils 17 are secured to the upper portions of the sections at 81, the lower ends of the coils being secured to the lower portions of the sections at 32, the steam being dis- The upper ends of the the boss 36 formed thereon. The sections,

23 areformed with horizontal openings '23 which register, and provide chambers in 'm which the,manifolds are received, vertical openings 24 being formed in the sections to receive the pipes 25' that support the burners 24. The pipe 37 enters through a" suitable. opening in the back of the'last sec- 1 tion, forms a loop in the heating chamber,

then passes out through another opemng in the back, the loop being supported by a hanger 38 shown in Fig. 3. This pipe is used as a hot water supply for general family use.

A steam gage 39, safety valve 40 and the usual water glass 41 are connected to the apparatus.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1.
